2022 Chevy Trailblazer LS AWD and Fuel System Errors
I have a 2022 Chevy Trailblazer and after getting stuck in the mud, the AWD light came on. I took off every tire and hosed out and around the sensors with the negative disconnected from the battery for 30+ min, the error still persists.
It also shows Low Fuel (on red) with the 'low fuel' error message indication. When starting the car and running the OBD scanner, I could hear the fuel pump making a high pitched screech.
Has anybody had these issues? I'm pretty sure these error codes point to the fuel pump / system, unsure why no AWD error codes show despite there bring a code on the car display.
Note this car, at 40k miles, had it's ECM replaced as it was throwing codes for no reason.
Error Codes: P16D7, U18A2 and P12A6
Mileage: 60k (if that matters)
